October 2018 in “JCI insight” In this study, the researchers found that treatment with the JAK inhibitor tofacitinib in alopecia areata patients may reduce clonal CD8+ T cell expansions but does not eliminate them entirely, which could contribute to disease relapse.
January 2025 in “ACS Applied Materials & Interfaces” In this study, a nanoparticle system codelivering diphenylcyclopropenone and rapamycin successfully induced immune tolerance and promoted hair regrowth in a mouse model of alopecia areata, offering a promising new therapeutic strategy for this autoimmune condition.

January 2013 in “The journal of investigative dermatology/Journal of investigative dermatology” This study found that thymus transplantation in athymic mice resulted in T-cell-driven hair follicle depigmentation and loss, without multiorgan autoimmune disease, highlighting mechanisms of tissue-specific tolerance.
November 2022 in “Journal of Investigative Dermatology” This study implicates EGFR as a critical regulator of immune privilege and stem cell quiescence in hair follicles, suggesting a link between EGFR inhibition and inflammation-driven hair loss during cancer therapy.
July 2026 in “The Journal of Immunology” This study found that C3H mice with prior microbial exposure developed alopecia areata at a reduced rate and had fewer associated T cells compared to controls, suggesting that prior infections might attenuate autoimmune responses related to the disease.
